Baraka begins by reading, not a lecture, but an excellent short manifesto of sorts about the revolutionary responsibilty of art, and the dangers of absorption & exploitation by consumer-culture.
He insists that art is innately political, and artists therefore have an imperative to participate in, even envision and direct, the movement for personal & social transformation.
Q&A starts at around 10:20
(its a short manifesto) -- people raise a variety of issues relating to art & revolution, and Baraka comments. Peter Lamborn Wilson gives a brief hats off.
For instance, there is talk about the problem of revolution led by the middle class: people without the disipline and commitment necessary to sustain revolutionary action beyond the pressures of modern demands, comforts, and a seductive culture.
Thsi is all still incredibly relevant, and Baraka speaks with challenging and provocative clarity.
